Seeking for Water System Permeability for Fish in the Czech Republic
In the Czech Republic as well as in Europe, river fragmentation is one of the significant drivers, threatening survival of fish species, dependent on migration. Particularly transverse barriers on water courses are physical obstacles partially or fully impending migration of water organisms.

Scenario of vegetation zone changes in the Czech Republic: ten years after
The regional scenario of climate change on the territory of the Czech Republic (Kalvová & Brázdil 1993) was the starting point for considerations on the effect of global climate change on the vegetation in the Czech Republic.

Study on the global climate impacts at the ecosystem level
The carbon cycle is of fundamental importance for the biosphere as it is inseparably connected with the climate, water and nutrient cycles and the biomass production on the land and in the oceans. It is useful to recall that carbon is one of the most important crossroads of the non-living and living world.

Biodiversity conservation at the close of modern times
The inhabitants of Europe did not go to bed one evening in the Middle Ages in 1492 to suddenly awaken into the Renaissance the next day; nonetheless, within only a few decades, at the end of the 15thand beginning of the 16thcentury, there was a substantial change in attitudes towards God, society, production, trade over large distances, human migration, the development of cities and landscape perception.

Biological diversity and climate change
Climate is the weather averaged over a long period of time determined by energy balance, cycles in the atmosphere and in oceans and by land cover patterns. The climate changes are not caused only by natural processes. According to the Intergovernmental Panel for Climate Change (IPCC), most of the observed increase in global average temperatures since the mid-20thcentury is very likely (the assessed likelihood, using expert judgement, is over 90 %) due to the observed increase in anthropogenic greenhouse gas (GHG) concentrations.

Biodiversity and climate change in the European Union
Biodiversity & ecosystem services and climate change are closely linked. The impacts of climate change on biodiversity present new challenges for nature conservation. Adaptation measures will be necessary to ensure the achievement of nature conservation objectives under changing climatic conditions.
